Will using Website Optimizer improve my landing page quality? Using Website Optimizer to experiment with your landing page does not have any impact on your Quality Score or your landing page quality. Website Optimizer evaluates your conversion rates to tell you which marketing messages are converting most often on your landing page, whereas the Quality Score doesn't incorporate any conversion information. Please remember that once you've made a change to your landing page based on tests run with Website Optimizer, the Quality Score may change as with any other changes to your landing page. We hope this helps to clear up some of your questions about this recent change. If you have additional questions, please let us know and we'll answer as many as possible the next time we write about landing page quality. http://payperclick-india.blogspot.com/
